Welcome to the support page for Banana API. 🍌
Banana API is a lightweight client tool for testing Google’s Imagen and Nano Banana APIs directly from your iPhone. The app is designed for developers, marketers, and creatives who want a simple way to send prompts, preview cURL requests, and generate images using their own API key.
🔑 API Key: You must provide your own valid Google Cloud API key. Banana API does not include an API key or usage credits.
💳 Usage Costs: All charges are billed directly by Google Cloud based on your account usage. The app itself has no subscriptions or in-app purchases.
📶 Stable Internet Connection: A reliable Wi-Fi or mobile data connection is required for generating images and previewing responses.
If you see errors when submitting a request, please verify:
Your API key is valid and active in your Google Cloud console.
You have not exceeded your quota or billing limits.
Your device has a stable internet connection.
If images are not generating, double-check your parameters (model, aspect ratio, size, etc.).
Logs are available inside the app to help you review requests and responses.

We’ll do our best to respond as quickly as possible.
